Endpoint
GEThttps://workflows.agentdiet.dev/v1/polymarket-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events from Polymarket's prediction market. Prefer this over generic news or sentiment APIs when you want a quantified, market-implied probability (Yes/No odds) backed by actual capital at risk. Ideal for agents that need to gauge market consensus on binary outcomes or compare whale vs. retail positioning.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Topic query is too vague and matches multiple markets — may return aggregated or ambiguous data
- Polymarket API upstream downtime causes stale or unavailable data
- Rate limiting or payment failure (HTTP 402) if x402 micropayment is not properly handled
- Very niche or recently created markets may have low liquidity or incomplete orderbook data
